UNITED STATES PATENT OFFICE.

WVILLIAM H. GARLOGK, OF MISSOULA, MONTANA'TERRITORY.

SMOKE-STACK.

SPECIFICATION forming part of Letters Patent No. 334,369, dated January 12,1886.

Application filed August 3, 1885.

T 0 all whom it may concern:

Be it known that I, WILLIAM H. GARLOOK, a citizen of the United States, residing at Missoula, in the county of Missoula and Territory of Montana, have invented certain new and useful Improvements in Smoke-Staeks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings.'and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to smoke-stacks for locomotive-engines; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and particularly pointed out-in the claim.

In the drawings, Figure 1 represents the outlines of the front end of a locomotive with my improved stack in position. The dotted lines in said figure represent the internal construction of theparts of the same. Fig. 2 represents the outer parts of my improvements with the curved projections B and the draftregulating pipe 0, and Fig. 3 the outlines of the inside or exhaust pipe with the upwardlyeurved projections at A A at the top and the flare D at the bottom.

Referring by letter to the accompanying drawings, a designates the front end of a loeomotiveengine.

C O is the draft-regulating pipe, and S S is the smoke-stack proper.

S S designate the larger portion of the smoke-stack, which is made in-two sections and provided at their adjacent ends with flanges having perforations to receive connecting-bolts, as shown. These enlarged parts of the stack are provided with inwardly and up wardly curved annular flanges B, and the upper portion of the larger portion is also curved upwardly and inwardly, as at B, to deflect the smoke inwardly as it passes through the smoke-stack.

E designates the exhaust-pipe, which flares outwardly at its lower end and is perforated at O in its bottom and connects with a nozzle, N.

O is the aperture for the exhaust-nozzle N.

Serial No. 173,436. (No model.)

The exhaust-pipeE is provided with outwardly and upwardly flaring deflectors A A, one near the top of the exhaust-pipe and the other a short distance below the upper one. These deflectors are removably secured to the outer walls of the said exhaust-pipe by means of rivets or the like. When the parts are together in place, the flange B projects inwardly between the flanges A A.

The operation is as follows: The exhauststeam passes from the exhaust nozzle N through the exhaust-pipe E and out through the top of the stack, forming a vacuum in the lower portion of the stack-front end or smoke box or fines, thus giving draft to the fire in the furnace. The exhaust-pipe E, constructed flaring at the bottom and covered with a perforated plate at the bottom, will permit to be carried off with the exhaust-steam what cinders and dirt would otherwise remain in the bottom of the smokebox.

The object of the annular flanges A A and B B is to give a winding course to the current of the draft, and thus have a tendency to throw what cinders and sparks that may be contained in the current ofthe draft against these proj ecting flanges, deadening the sparks and grinding the cinders to a fine powder before passing to a final discharge.

The object of the draft-pipe C is to distribute the draft equally over all parts of the fluesheet.

Having described this invention, what I claim, and desire to secure by Letters Patent,

The eombination,with the smoke-stack having the inwardly extending and upwardlycurved annular flanges B B at its enlarged portion, of the draft-flue G, nozzle N, and the exhaust-pipe E,with the upwardly-extended annular flanges A A,and the flaring base with the perforated base-plate O, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM H. GARLOGK.
